Will You Live to Be 100? Check Your Genes

Boston University scientists believe they may have uncovered the secret to why some people live to be 100 years old. According to a new report, published in Science by the New England Centenarian Study at Boston Medical Center, scientists may have have pinpointed the gene for long life. Researches found that 40 percent of those who live to be at least 110 shared three genetic signatures. The director of the study, Dr. Thomas Perls, talks to us about the findings and how they may change medicine.
